Long time no posts, and no kr1 time

Finally got is stripped, and as suspected the head was warped on both cylinders on the upper side between the combustion chamber and the long coolant slot. Got is skimmed, so ready to re-assemble with 2 genuine base gaskets to regain swish, and a genuine head gasket.
Question is - dry gasket assembly, or a smear of Kawabond, or is there something else I should be using ?
Thanking you

Tommy
